Mr. President, Tear Down This Wall: Why Walls Won't Work

"Nearly 700 miles of walls now separate the United States and Mexico. Would-be migrants still find ways over, under, through and around them. As a tool for controlling immigration to the United States, the border fortifications have been remarkably ill suited to the task. And yet these barriers are having a significant and lasting effect nonetheless: they are harming communities on both sides of the border. We should tear them down before the damage becomes irreparable." - Prof. Michael Dear, Mar. 11, 2013.
